Bearing definition
Calculated geometry and production-oriented definition.
Public AURA engineering case
A calculated bearing carried into the shaft and unbalance-response model.
This case connects three deliverables produced in one engineering chain: an AURA-generated bearing definition, the selected support state in the shaft and rotor model, and the response of that system under a defined unbalance.
01 · BEARING DEFINITION
AURA-generated production-oriented bearing definition.
The calculated cylindrical aerostatic bearing is carried into a drawing that records the bearing geometry, feed arrangement, dimensions, tolerances, material, inspection basis and prototype manufacturing review state.
- Bearing length: 80.0 mm
- Functional clearance: 30.0 µm
- Bore: 60.0 mm
- Eight Ø0.500 mm feed holes per row
02 · SHAFT AND ROTOR MODEL
Selected bearings carried into the shaft and rotor model.
The bearing result becomes a support definition for the shaft. AURA places the selected bearings, shaft geometry, support locations and reactions into the rotor model so that modal and machine-level consequences can be calculated.
The public model shown here identifies the rigid-translation mode and the support layout before the forced-response calculation.
03 · RESPONSE-DOMAIN ENGINEERING
Unbalance response of the selected shaft-bearing system.
The selected shaft-bearing system was then evaluated in the time domain under a defined unbalance at 12,204 rpm.

The result demonstrates that AURA reaches beyond bearing sizing and modal screening into calculated forced response for the selected system.
Engineering chain
One selected support state, three connected deliverables.
Shaft model
Selected bearings carried into the rotor configuration.
Response
Time-domain displacement under defined unbalance.
Decision
Use the response to retain, revise or deepen the design.
